The Efeects Of Salivary Amylase On Starch Hydrolysis Under Different PH Levels

Introduction         Enzymes are catalytic molecules made up of proteins which bring forth up item reactions. Such reactions occur when atoms or molecules play to birthher and form new, more(prenominal) stable relationships. Enzymes are not for good altered or used up in a reaction; they can be used oer and all over again. An enzyme is also highly selective of its substrates. Substrates are molecules that a special(prenominal) enzyme can chemically recognize, bind, and modify in a special(prenominal) way, which in this experiment, are the starch molecules(Starr, 1994).         The procees by which strarch is blue mound is called starch hydrolysis. When this occurs, polysaccharide starch molecules are overturned subject into modified forms known as disacharides. This process is worked up by the salivary enzyme within the mouth which catalyses polysacharides into maltose, a disaccharide. malt ice lolly is whence further broken down i nto simple sugars(glucose) by maltase, another enzyme.         These reactions however occur only under specific environental conditions provided within the mouth. This experiment assesses at which pH level salivary amylase works best under, in the breakdown of starches, with the pH of 7 (average pH level found within the mouth) hypothesized to be more efficient in starch hydrolysis by salivary amylase.

Materials and Methods          art object waiting for the spectrophotometer to warm up at a wavelength of 560nm for at least 20 minutes, the following tasks were performed. A test tobac co pipe rack was obtained containing 3 rows ! of 11 testtubes. Each of the 3 rows were labeled according to the pH levels of 5.0, 7.0, and 8.0. All 11 tubes in each row were then labeled in root to seconds: 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, and 300. A blank tube was obtained and 3 mL of distilled pissing and 1 drop of cat valium iodine was dilute into the tube. The enzyme collected in this...
